Upgrade your Toyota GR Supra with this premium cat-back exhaust from HKS — one of the most respected names in high-performance exhaust engineering.
HKS exhaust systems are rooted in motorsport heritage and engineered for performance, quality, and long-lasting durability. The Hi-Power design offers the perfect balance of everyday usability and thrilling performance sound — a signature upgrade that complements both street driving and spirited track use.
High-Flow Design: Engineered with larger diameter piping (approximately 85mm to 70mm) for significantly improved exhaust flow over stock, supporting future upgrades.
Distinctive Sound: Tuned through extensive sound frequency analysis to deliver a deeper, richer, and more aggressive exhaust note — louder than stock (90dB at idle vs 88dB stock) without unpleasant drone.
Valved System Compatibility: Fully compatible with the factory exhaust valve actuator and controls, so you retain stock-style quiet cruising and open-mode performance sound.
Premium Materials: Constructed from high-quality SUS304 stainless steel with eye-catching dual 120mm burnt titanium tips that enhance the rear styling.
Performance Potential: Designed to reduce back pressure and improve turbo response; internal testing and dyno results have shown power gains of 30+ horsepower with supporting mods.
Lightweight: System weight is reduced compared to stock, helping lower overall vehicle mass and improve responsiveness.
